sounds like the new alt. has a bad internal regulator

will it start with a jump? take a meter to the battery test battery voltage. should read 12-13v , start the car the voltage should read 13-16v if the voltage doesn't go up then the alternator is shot if the voltage goes up the battery is shot.or needs deep cycle charge
